Alaid exposes high potential hazard to the aircrafts flying over Kamchatka and the Northern Kuriles because its eruptive clouds can rise to a height of 10-15 km above the crater and extend for hundreds of kilometers (up to 1500 km) and the duration of eruptions can exeed a few months.

Ash falls possible at:

Severo-Kurilsk (45 km to the south-east from the volcano)
Ozernovsky (90 km to the north-east)
Ust’-Bolsheretsk (215 km to the north-north-east)
Petropavlovsk-Kamchatsky (310 km to the north-east)
